Filter by:This study will determine the functional status of the nasal immune environment with LAIV exposure in COPD persons with frequent exacerbations (defined as individuals with two or more episodes of worsening in COPD symptoms requiring treatment with antibiotics and/or steroids in the prior 12 months) and COPD persons without frequent exacerbations to determine acute exacerbation of COPD (AECOPD)-associated dysfunction in a) cytokines and immune effector cells of the nasal mucosa and b) viral replication. The investigators hypothesize that: 1) COPD frequent exacerbators, compared to COPD infrequent exacerbators, will demonstrate altered mucosal immune responses to LAIV exposure, and 2) COPD frequent exacerbators, compared to COPD infrequent exacerbators, will demonstrate increased markers of influenza viral replication after LAIV exposure.
This study evaluates the effectiveness of a Mindfulness-Based Stress Reduction intervention (MBSRI) on the reduction of stress, anxiety, and depression in people with COPD and their family caregivers. The experimental group will receive the MBSRI and the control group an informational intervention on stress management.
The ELVIS study compares the nasal high-flow to non-invasive ventilation in treatment of acute acidotic hypercapnic exacerbation of chronic obstructive pulmonary disease.
Chronic diseases are frequent (around 10% of the total population and 30% after 60 years) and accelerate age-related functional decline. Concerning cross-border patients, use of health services can be delayed given the distances, the lack of rapid road access and the limited availability of public transport and the complex organization of coordinated care. One of the ways to reduce acute exacerbations and preserve the quality of life of patients is to detect warning signs early. One of the ways to do this is to use new communication technologies.
The overlap between chronic obstructive pulmonary disease (COPD) and bronchiectasis is a neglected area of research, and it is not covered by guidelines for clinical practice. COPD and bronchiectasis share common symptoms of cough with sputum production and susceptibility to recurrent exacerbations driven by new or persistent infection. Physiological criteria for the diagnosis of COPD and structural criteria for the diagnosis of bronchiectasis create the possibility for individual patients to fulfil both, resulting conceptually in either co-diagnosis or an overlap syndrome between the two conditions. The prevalence of this overlap will vary depending on the respective prevalence of COPD and bronchiectasis in the population under consideration. A recent study of 201 COPD patients with airway wall abnormalities typical of bronchiectasis confirmed an association with exacerbations and was predictive of mortality over 48 months. A further, single-centre study demonstrated a near three-fold increased mortality rate, with patients with bronchiectasis and associated COPD having a 5-year mortality of 55%, compared with 20% in those with bronchiectasis without COPD. Airflow obstruction is perhaps best considered one marker of disease severity in bronchiectasis. Disease-associated exacerbations have a major effect on patient healthcare costs as well as quality of life due to increased lung damage and mortality risk. Microorganisms such as Pseudomonas aeruginosa and, to a lesser extent, other Gram-negative and Gram-positive microorganisms identified in culture, have been linked to disease progression, poor clinical outcomes in bronchiectasis and driving airway neutrophil-mediated inflammation. The microbiome has the potential to provide valuable information regarding disease phenotype/endotype, treatment responses and targets for future therapy.
This study aims to objectively evaluate the clinical efficacy and safety of Traditional Chinese Medicine in the treatment of AECOPD Risk Window, providing a basis for the formulation of TCM treatment plan with AECOPD.
This study will last for 5 years (2021.2.25-2025.12.31). 210 patients (70 cases in each group) will be enrolled in this study. Eight centers in China will participate in the study. The patients will be treated with bronchoscopy alveolar lavage, and 60 ml of bronchoalveolar lavage fluid will be collected for the next-generation sequencing of airway microorganisms. The patients will be followed up for 4 years to observe the changes of lung function, Fractional exhaled nitric oxide (FENO) and clinical symptoms.
This investigator-initiated, prospective, single center, randomized, controlled clinical trial enrolled patients with stable Global Initiative for Chronic Obstructive Lung Disease stage II-IV chronic obstruction pulmonary disease. The primary outcome was 2-year acute exacerbation rates.
Patients with moderate to severe acute exacerbation of chronic obstructive pulmonary disease are often complicated with hypercapnia and respiratory failure, so they need to be admitted to ICU for monitoring and respiratory support treatment. Noninvasive ventilation has become the first-line respiratory support for the treatment of AECOPD with hypercapnia and respiratory failure. However, 26-54% of AECOPD patients with hypercapnia and respiratory failure eventually fail to receive noninvasive ventilation and need endotracheal intubation and invasive ventilation to maintain effective gas exchange. For these patients, the in-hospital survival rate is only 31-76%, and the prognosis is poor. In AECOPD patients with high risk of noninvasive ventilation failure and expected need of intubation, timely giving other ways of respiratory support to reduce blood CO2 may avoid patients receiving tracheal intubation and invasive ventilation, thus avoiding related complications and adverse prognosis. As a new type of respiratory support technology, ECCO2R is worthy of attention in monitoring and evaluation of support effect in AECOPD patients with respiratory failure. It is urgent that ECCO2R can effectively alleviate respiratory failure, avoid complications related to tracheal intubation, improve quality of life and reduce mortality.
Chronic obstructive pulmonary disease (COPD) is a common disease that endangers people's health, causing severe economic and treatment burdens. Sleep breathing disease, as a complication of COPD, increases the hospitalization rate and mortality of COPD. At present, community doctors have insufficient knowledge of COPD and its complications, and they also lack standardized screening and related disease management capabilities. This trail intends to use IoT medical technology to screen for COPD combined with sleep breathing diseases. It can establish a two-way referral channel between primary community hospitals and higher-level hospitals, which provides early warning services for COPD combined with sleep breathing diseases. This trial explores the impact of sleep breathing disease on COPD's acute exacerbation, which improves the understanding of COPD patients combined with sleep breathing diseases. It also improves COPD management and its complications control at the community-level and reduces COPD patients' potential risks and treatment burdens. It also explores tiered diagnosis and treatment models for COPD, promotes the construction of intelligent IoT infrastructure, and enhances standardized diagnosis and treatment of COPD at the grassroots level in China.
